Part #2 - C programmers.. need assistance.

[[N]auTiCa]

thanx quadz.. I'm understanding what needs to be done, but my problem is that I don't know how to output m_pNote to the preview window?

[[N]auTiCa]

This is driving me nuts.. I cannot understand this shit and I'm getting restless, almost 3am.. excuse the language 

would something like this seem adequate?

Code: [Select]

void CDlgRecycleBin::Preview(CString szFile)
{

POSITION pos;
CString szXML, szTemp;
CRect rc1, rc2;

if (theApp.m_bSortRecycleBinDescending)
pos = m_pNote.GetTailPosition ();
else
pos = m_pNote.GetHeadPosition ();

POSITION delpos;
int rgIndex[BUFFERSIZE];
m_pTitle.GetSelItems (BUFFERSIZE, rgIndex);
int iRow = 0;
int iCount = 0;



[console]

Hmm..

Well... take a look at:

Code: [Select]

void CDlgRecycleBin::DeleteMarkedNotes ()
{
POSITION pos;

if (theApp.m_bSortRecycleBinDescending)
pos = m_pNote.GetTailPosition ();
else
pos = m_pNote.GetHeadPosition ();

POSITION delpos;
int rgIndex[BUFFERSIZE];
m_pTitle.GetSelItems (BUFFERSIZE, rgIndex);
int iRow = 0;
int iCount = 0;

while (pos) {
delpos = pos;
tagNote note;

if (theApp.m_bSortRecycleBinDescending)
note = m_pNote.GetPrev (pos);
else
note = m_pNote.GetNext (pos);

if (iRow == rgIndex[iCount]) {

m_pNote.RemoveAt (delpos);
iCount++;
}

iRow++;
}
}

I mean, basically, you're dealing with a crappy Microsoft version of the STL.  Unfortunately, the STL, like Unix, was written by people with big-picture ideas of how a whole system would work.  Which would be great, if only you could use the STL or Unix.  But instead you're stuck with Microsoft, which was put together apparently by various smart people with no big-picture ideas and it's a big wasteland of poorly-cooperating co-existing system fiefdoms.  . . . Errr....

Well, anyway... 

What ???

[[N]auTiCa]

lol.. damn microsoft!

so do I create something like..

Code: [Select]

void CDlgRecycleBin::PreviewNotes ()
{
POSITION pos;

if (theApp.m_bSortRecycleBinDescending)
pos = m_pNote.GetTailPosition ();
else
pos = m_pNote.GetHeadPosition ();

POSITION delpos;
int rgIndex[BUFFERSIZE];
m_pTitle.GetSelItems (BUFFERSIZE, rgIndex);
int iRow = 0;
int iCount = 0;

while (pos) {
delpos = pos;
tagNote note;

if (theApp.m_bSortRecycleBinDescending)
IDC_Preview = m_pNote.GetPrev (pos);
else
note = m_pNote.GetNext (pos);

if (iRow == rgIndex[iCount]) {

m_pNote.RemoveAt (delpos);
iCount++;
}

iRow++;
}
}

dude.. I'm lost, I can imagine your laughing at my modified version of the above code... 

I'm trying to figure out where IDC_Preview would go so that whatever is selected will be outputted to the preview pane.

[console]

pos = m_pNote.GetTailPosition ();
else
pos = m_pNote.GetHeadPosition ();

POSITION delpos;
int rgIndex[BUFFERSIZE];
m_pTitle.GetSelItems (BUFFERSIZE, rgIndex);
int iRow = 0;
int iCount = 0;



Well, that looks like a good start, actually!

From that point you could easily find, say, the FIRST selected element... and look up the note for that element index... and get the tagNote data structure from that note.

And to think I didn't know what I was doing... hahah

anyways...

would adding a line like:

if (m_pTitle.GetCount () == 0)
      return;

CString szImport;
   szImport.Format (_T("%s\\import.xml"), GetApplicationDataPath ());
   CreateImportXml (szImport);

   IDC_Preview (szImport);

work? ..i took that from the OnRestore function.

btw.. have you actually completed this assignment? I'm assuming something like this would take you 10 mins to complete, if not less than that.

Any other hints or suggestions quadz.. I'm about to get some sleep, almost 4am and what I have thus far obviously doesn't work, so I'll try and wake up early and clean up any code that is wrong, although I don't think I'll successfully complete it.

If you have anything else to share, please do! I need this part of the project to help cushion my somewhat poor performance on the first part 

Let me know, I'll be off within the next half hour.. thanx again for your help on this one, I'm sure it's getting late for you too.

p.s. just forward me your code lol ~ 

[console]

Hmm.. Well I guess it's too late, then

But essentially... when your dialog gets an ON_LBN_SELCHANGE event for the list box... You could ask for the selected items,  if there's more than one item, you could just display "(multiple selection") or somesuch in the preview pane.  If exactly one note title is selected in m_pTitle, then take that index number and find the corresponding tagNote data in m_pNote... and SetWindowText the note data into the preview pane edit box.

I technically still have two more hours before I have to turn this in.. if your around, I can still use some help!
